Application filed October 16, 1917.

To all whom it may concern:

Be it known that 1, JOHN A. KAsznwsKI, a citizen of Poland, Russia, and a resident of the city f Chicago, county of Cook, and State of Illinois, have invented a certain new and useful Milk-Bottle-Locking Device,

' of which the following is a specification.

My invention relates to milk bottle looking devices, that is to that class of devices, the purpose of which is to prevent theft of milk bottles after delivery of the same by the milkman and before the rightful owner or recipient of the bottle calls for the same at the place of delivery thereof by the milkman.

The object of my invention is the production of a device of the character mentioned, which may be of durable and economical construction and through the medium of which a milk bottle may be effectually locked.

A further object is the production of a device of the character mentioned which may be readily and easily operated.

Other objects will appear hereinafter.

The invention consists in the combinations and arrangements of parts hereinafter described and claimed.

The invention will be best understood by reference to the accompanying drawing forming a part of this specification, and in which,

Figure 1 is a side elevation of the device showing the same in position of use or with a bottle arranged in operative relation therewith,

use in connection with a door frame illustrated at 15 and the usual hinged door illustrated at 16. Upon the door frame 15 is arranged 'a base plate 17 rigidly secured thereto by screws 18. The plate 17 is formed adjacent its upper end with forwardly projecting spaced ears or lugs 19, in which is arranged a pin or bolt 20, which is adapted for pivotal as well as longitudinal shifting movement. An overhanging flange or cap 21 connects the upper edges of ears 19 as seen in the several views.

Swingingly mounted upon the pin 20 is a aw carrier 22 formed of a single piece of sheet metal bent upon itself so as to form two spaced parallel portions, said portions being connected by bands or straps 28, which pivot-ally embrace the pin 20. Arranged between the spaced portions of member 22 and pivotally connected therewith at 24k are jaws 24 of such shape as to be adapted, when at their inner terminals of movement, to embrace the neck of a conventional milk bottle shown at A, in order to lock the bottle to the device. The jaws 24 are formed with intermeshing teeth 25, as seen in Fig. 5', which result in simultaneous movement of said jaws, as will be readily understood. Shoulders 26 and 26 at the inner ends of said jaws limit outward swinging thereof, and shoulders 27 and 27 are adapted to engage against the inner sides of ears or lugs 19 to limit inward swinging of said jaws. Above said jaws is provided a sort of guard 28 to prevent removal of the milk bottle cap. The member 28 is rigidly secured to the aw carrier 22.

Cooperating with the jaws 2 1 is a latch 29, the same being formed at its ends with ears 29' as seen in Fig. 8, which pivotally embrace the pin 20, said latch being adapted to fit snugly between the portions 23 of the jaw carrier 22. The forward or free end of the latch 29 is adapted to engage between shoulders 30 on the aws 2A in order to lock said jaws in operative relation, that is at their inner terminals of movement. Cooperating with said latch is a leaf spring 31 arranged under the cap 21, said leaf spring being adapted to engage with a lug or projection 32 on the latch in order to normally press said latch toward operative position. The ears 29 of said latch project, at their under sides, beyond the portions 23 of the jaw holder 22, said ears being formed with shoulders or points 33 which are adapted to engage against the base plate 17 in order to limit pivotal movement of said latch to-- ward said plate. The arrangement is such that, as the jaw carrier is swung downwardly toward vertical position, the shoulders 33 will engage against the base plate 17 and serve to raise the free end of said latch to a position out of operative relation with the shoulders 30 of'the jaws 24, as is clearly seen in Fig. 4:. This being the case, when the jaw carrier is in depending vertical position, or idle, the jaws 24: will be released so as to permit outward swinging of the same. Immediately upon said jaw carrier being swung toward raised or horizontal position, which is the operative position thereof, the shoulders 33 will be moved from engagement with the plate 17 to permit of the free end of the latch being rocked, under the influence of spring 31, to a position between the shoulders 30 of the jaws 2%, as clearly seen in Fig. 3. T his being the case, when the device is swung upwardly, a bottle arranged therein, and the jaws 2irocked inwardly into engagement with the bottle,

the latch 29 will autoi'natically, under the influence of spring 31, move to operative position where the same will lock said jaws in bottle-engaging position.

In order to effect movement of the latch to inoperative position, that is to a position to release the aws 24, the pin 20 is provided with across piece 3%, as is clearly seen in Figs. 3, 4: and 6. Said cross piece 34, when the pin 20 is at its left hand or inner terminal of movement, engages with a ledge 35 formed upon the jaw carrier 22, which prevents any rockin movement of said pin. When said pin is pulled out to its right hand or outer terminal of movement, the cross piece 34 will be brought into registration with a notch 36, which will allow for rock ing of said cross piece and hence the pin 20. One end of said cross piece is adapted to engage against the under side of latch 29 so that when thus rocked, said cross piece will rock said latch to releasing position. Thus, in order to unlock a bottle once locked in the device, it is necessary to pull the pin 20 to its outer terminal of movement and then oscillate the same in order to move the latch 29 to releasing position. The device is, however, so arranged that when the door 16 is closed the pin 20 will be locked thereby at its inner terminal of movement. This being the case it will be seen that in order to unlock the device to release a bottle therefromit will first be necessary to open the door in order to permit of shifting of the pin 20 to its outer terminal of movement.

In using the device then it will be seen that when the same is in depending vertical position, or idle, the jaws will be free for movement as desired. Thus, the milkman in delivering the milk, needs only to rock the jaws outwardly with the device in idle position, then swing the device upwardly, in sert the bottle, and press the jaws inwardly into operative relation with the bottle. The

capable of variation and modification with-' out departing from the spirit of my. invention and I therefore do not wish to be limited to the precise details of construction set forth but desire to availmyself of such variations and modifications as come within the scope of the appended claims.
